They did wind up in bankruptcy. The last I remember the stock was being quoted at pennies a share. I know McDonalds bought them I don't know what happened to the shareholders.
My only basis for mentioning BM though was in the context of suggesting that KKD could be a buyout target. I haven't even looked at their financials so I don't know how bad they are but I do think there is an enormous amount of value in their brand and their product probably about 50 times what the boston market brand was worth at least.
If it does ultimately go sub 1 dollar I will be taking a very hard look at the financials and bankruptcy. I took a peek at HLSH near its bottom and regreted not getting in.
Markets tend to overreact both to the positive and negative and that creates buying opportunities. I think that one is worth keeping an eye on in case such an opportunity crops up.
Its just a good product I can't imagine it just vanishing.
